Cryptomator and FTPie both exist so that your cloud provider can't read your files - but they get there by very different routes, and for some people the honest answer is "use Cryptomator, it's free." Here's how the two models actually differ, so you can pick the one that matches how you work.
Cryptomator creates an encrypted vault - a folder of scrambled files that lives inside your Dropbox, Google Drive, or OneDrive sync folder. Unlock the vault with your password and it appears as a virtual drive; everything you drop into it is encrypted transparently, filenames included. Your cloud's sync client uploads only ciphertext.
FTPie is a file manager for cloud, FTP, SFTP, WebDAV, and NAS that includes per-file AES-256 encryption in its transfer layer. You encrypt specific files or folders on demand - locally or on any connected storage - and they're sealed as individual .ftpie files anyone can decrypt with the password in the free version of FTPie.
